Breathing - as with adult, refers to rescue breathing, where one person is breathing into other or also commonly referred to as mouth to mouth technique.

1.  Keep the heel of your hand in place so the infant's head remains tilted.  Keep your other hand under the person's chin, lifting it up.

2.  Take a normal breath, cover infant's mouth and nose with your mouth (Difference 2), and give 2  gentle breaths until the chest rises (blow for one second each).  Observe baby's chest.  Stop blowing when the chest rises, and wait for the chest to fall before beginning another breath.  If chest is not rising, readjust the head-tilt/chin-lift position and try two more breaths. Goal is for the child to receive two full mouth to mouth breaths, 1 second each.

3. Once done with rescue breaths you must check the infant for pulse by placing your index and adjacent fingers on the victim's brachial artery. (Difference 3)

4. If there is no pulse, proceed to C.                

Important: Do not give large, forceful breaths, adhere to one second limit per breath.  Proper breathing administration is extremely important for infants, make sure the breaths are sufficient to make the chest rise. Monitor the chest while administering mouth to mouth.
